MACHINE FOR CUTTING WASHERS.

SPECIFICATION forming part of Letters Patent No. 613,363, dated November 1, 1898.

Application filed November 29, 1897. Serial No. 660,159. (No model.)

To all whom it may concern.- I

Be it known that I, MICHAEL V. DOYLE, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Machines for Cutting WVashers, of which the following is a specification.

This invention relates to improvements in washer-cutting machines in which a foot is adapted to hold a piece of leather outside of the section from which the washers are cut and made Vertically and horizontally adj ustable, also a spring-foot supported bya rotating cutter-head.

In the accompanying drawings, Figure 1 is an isometrical representation of my improved washer-cutter. Fig. 2 is an under face view of the cutter-head. Fig. 3 is an isoinetrical representation of the work-supporting shelf. Fig. 4; is an isometrical representation of one of the cutters. Fig. 5 is a vertical section through the foot 25 and its connection with the standard.

My improvements are applicable to the general construction of machine shown in Letters Patent granted to me Augustt, 1885, No. 323,860--machine for cutting washers-the standard or support 1, verticallymovable portion 2, operated by the hand lever 3 through the link connection 4, and the rotatable shaft 5 being the same as shown in said patent. From the platen extends a groove guideway 6, which serves to support a shelf '7 by a guide 8, located in the guideway. This connection permits the shelf being moved to- From the edge of the shelf extends a notched plate 9. To the platen is secured an arm 10, and to its free end is secured a lever 11, having a projection 12, adapted to enter the notches of the plate 9, by which a connection is formed between the shelf and platen in an adjustable manner. From the upper face of the shelf extends a gage 13.

The standard 1 supports a bracket 14 in a vertically-adjustable manner by the slots 16 and screw-bolts 17. This bracket supports a block 18, adjustable in connection therewith by the slots 19 and screw bolts 20, and

this block has its outer face vertically grooved in the form of a guideway. A guide 21 moves vertically in the guideway of the block 18, a pin 22 limiting its downward movement, and a spring 23 has a connection with the guide at one end, its other end being connected to a projection 24, extending from the bracket 14. To this guide 21 is secured a foot 25, having an opening 26, located centrally under the rotating shaft 5. A cutter-head 27 is secured to the lower end of the rotating shaft 5, having circular vertical openings 28. In some of these openings are secured shanks 29, supporting cutters 30. an adjustable manner by.the set-screws 31, and the cutters are held in an adjustable manner by the set-screws 32. These knives are so adjusted that the one nearest the center of the head is the longest and the one farthest fromthe center is the shortest.

A foot 33 is secured to a shank 34, located in one of the openings 28 and held in an adjustable manner by the set-screws 35 and 36-. This foot is of spring material in order to be made yielding and is so adjusted with relation to the knives as to extend from the center of the cutter-head outward in a radial manner.

The knives are adjusted to cut the required sizes and number of washers, and the shelf is adjusted to properly locate the leather under the knives. The leather is placed on the shelf against the gage. The platen is then raised, which will bring the leather against the foot 25, which will rise vertically, allowing the foot 33 to press on that portion of the leather to be cut out, and the further raising of the platen will bring the leather against the cutters of the rotating cutter-head. The cutter nearest the center of the head will cut its washer first, and the cutter farthest from the center of the head will cut its washer last, and as the foot 33 rotates in contact with the leather forming the washers before and after being cut it will impart a finish to the complete washer and also hold the leather in a manner to allow the knives to free themselves therefrom.

The foot-plate 25 can be varied in size to conform to the size of washers out and is adjustable horizontally by adjusting its sup- The shanks are held in port 18 in order that the opening 26 may be brought centrally under the cutter-head.

I claim as my invention- 1. In a washer-cutting machine, the combination of a suitable support provided with a horizontal guideway, a Work-supporting shelf fitted to move in the guideway having a toothed rack along one edge, an arm provided with a projection, the projection adapted to enter the notches of the rack, a vertical rotary shaft, and a cutter secured to the lower end of the shaft.

2. In a washer-cutting machine, the combination of a Work-supporting shelf, a rotary cutter and a foot supported in vertical guideways and located between the cutter and shelf and made horizontally adjustable.

3. In a washer-cutting machine, the coinbination of a work-supporting table and a rotary cutter-head, the head provided with 20 MICHAEL V. DOYLE.
